Answer 1

saving image...
ImageIcon icon=(ImageIcon)StyleConstants.getIcon(attr);
if (icon!=null) {
int w=StyleConstants.getIcon(attr).getIconWidth();
int h=StyleConstants.getIcon(attr).getIconHeight();
ByteArrayOutputStream os=new ByteArrayOutputStream();
PNGCodec p=new PNGCodec();
ImageEncoder pe=p.createImageEncoder("PNG",os,null);
BufferedImage bi=new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);
bi.getGraphics().drawImage(icon.getImage(),0,0,null);
pe.encode(bi);
byte[] ba=os.toByteArray();
int len=ba.length,i;
StringBuffer sb=new StringBuffer(len*2);
for (i=0;i<len;i++) {
String sByte=Integer.toHexString((int)ba[i] & 0xFF);
if (sByte.length()<2)
sb.append('0'+sByte);
else
sb.append(sByte);
String s=sb.toString();
out.write("{\\pict\\pngblip ");
out.write(s);
out.write("}");
extracting image
String content; //<- image representation
int len=content.length();
//converts to binary representation
byte[] buf=new byte[len/2];
for (int j=0; j<len/2 ;j++) {
String c1=content.substring(j*2,j*2+1);
String c2=content.substring(j*2+1,j*2+2);
byte b1=Byte.parseByte(c1,16);
byte b2=Byte.parseByte(c2,16);
buf[j]=(byte)(b1*16+b2);
//creates image from binary
Image img = Toolkit.getDefaultToolkit().createImage(buf);
ImageIcon icon=new ImageIcon();
icon.setImage(img);
if ((icon.getIconHeight()<0) || (icon.getIconWidth()<0))
return;
MutableAttributeSet attr=new SimpleAttributeSet();
StyleConstants.setIcon(attr,icon);
//inserts image in the document
document.insertString(currentOffset," ",attr);
currentOffset++;
